SPECIFICATION forming part of Letters Patent No. 609,311, dated August 16, 1898.

Application filed January 20, 1898. Serial No. 667,212. (No model.)

To cir/Z whom t may concern: l

Be it known that I, LEWIS E. WATERMAN, a citizen of the United States, residing at Moline, in the county of Rock Island, in the State of Illinois, have invented a certain new and useful Improvement in Sulky-Plows, of which the following is a description, reference being had to the accompanying drawings, forming part of this specieation.

My invention has for its object the provision of novel means controlled by a single lever for raising and lowering both sides of the machine simultaneously to regulate the depth of furrow being plowed, while at the same time permitting adjustment of the land-wheel independently of the furrow-wheel by means of a separate lever when necessary, and its novelty will be hereinafter set forth, and speciiically pointed out in the claims. f

In the accompanying drawings, Figure 1 is a perspective view of a sulky-plow embodying my improvements; Fig. 2, an enlarged detail perspective view showing the means for adjusting the wheels on the opposite sides of the machine to raise and lower the plow, and Fig. 3 a sectional detail of the extreme left-hand' end of the crank-axle and the parts mounted upon it.

The same letters of reference are usedto indicate corresponding parts in the several views.

A is the main axle of the machine, which has mounted upon and connected to it the draft and plow beam B, whose downwardlycurved rear end carries the plow O. The landwheel D of the machine is mounted `upon the left-hand end of the crank-axle E, which axle, as shown in Fig. 2, has a bearing at F near its left-hand end in a clipA G, bolted to the; left-hand end of the main axle A. The axle E extends entirely across the machine, as shown in Fig. 2, and near its right-hand end (left-hand end in Fig. 2) is provided with a support and bearing hereinafter described.

Rigidly secured to the extreme right-hand end of themain axle A is a vertical plate II, upon which is mounteda slide I, which carries the axle or spindle. J, upon which is mounted the furrow-wheel K, Fig. l. The

slide I is connected by a link L with an arm M, carried by and in this instance formed inte` gral with a sleeve N, loosely mounted upon the end of the axle E. Rigidly secured to the vertical guide-plate H and main axle A is a sector-rack O, one ofthe rivets by which the rack is securedto the plate H being shown at a in Figs. 2 and 3. The end of the axle E and the sleeve N, surrounding it, pass through and have their bearing and support in the lower forward end or hub of the rack-plate O and are free to turn independently of each other therein.

Rigidly secured to or formed integral with the right-hand end of the sleeve N in Figs. 2 and 3 is a second rack P, while located between it and the rack O is the lower end of a lever Q, which is rigidly secured to the side of the rack P and is provided with a spring latch R,which cooperates with the rack O and is controlled'by arhandpiece S, pivoted to the upper end of the lever andconnected with the latch by a rod T, as usual.' Loosely mounted upon the axle E, immediately atthe right of the rack P in Figs. 2 and 3,`is a second lever U, provided with a springlatch V, which .cooperates with the rack P. l

Fast upon the axle E, at the right of the lever U, is an arm W, provided at its upper end with an eye b, through which and through a coincident eye in a laterally-projecting ear c upon the casting constituting the lower end of the lever U passes a rod X, which is surrounded by a strong coiled spring Y and is provided at its forward end witha `head oZ,'by which the spring Y is confined uponv the rod, a nut e, screwed upon the rear end of the rod X, serving to hold the parts together; By these means the lever U is yieldingly connected to the axle E but,so far as the novelty i of myinvention and the operation of the parts hereinafter described are concerned,the lever U may be rigidly secured at its lower end directly to theaxle E instead of being yieldin gly connected to it in the manner described.

As will be understood from the foregoing descriptiomthe rack O is rigidly secured to what may be considered `the frameof the machine-KL` e. the main axle A and the guideplate H, rigidly secured to its left-hand endwhile the arm M, sleeve N, lever Q, and rack P are allrigidly connected with each other and are moved together bythe lever Q, being held in their different adjusted positions by the engagement of the latch R of such lever with the rack O. It will be further understood that the lever U and axle E move together and are independent of the lever Q and parts moving with the latter, except as connected to them by the engagement of the latch V of the lever U with the rack P.'

It results from the foregoing that if the latch V of the lever U be disengaged from the rack P the lever U may be swung forward or backward to rock the axle E and raise or lower the land -wheel D, mounted upon its left-hand end, and the parts be held in the desired adjusted position by reengagement of the latch V with the rack P,while if the latch of the lever Q be disengaged from the rack 0 and the lever be swung forward or backward the sleeve N will be rocked and through its connection by the arm M and link L with the slide I will raise or lower said slide and the furrow-wheel K, mounted upon the spindle J, carried by said slide.

Inasmuch as the lever U and parts moving with it are normally connected with the lever Q and parts moving with the latter lever, (by the engagement of the latch V of the leverU with the'rack P, secured to the lever Q,) it follows that when the lever Q is swung forward or backward to raise or lower the furrowwheel K in the manner described the lever U will be carried with it, thereby rocking the axle E and raising or lowering the land-wheel D. In the manner and by the means described, therefore, the land-wheel may be adjusted independently of the furrow-wheel by independent manipulation of the lever U, while both wheels may be adjusted simultaneously by manipulation of the lever Q.

The spring Z (shown in Fig. l) is the usual spring for aiding in forcing the lever Q rearward when it is desired to lower the wheels and lift the plow. It is connected at its upper end to the lever Q and at its lower end t-o theupper end of a curved arm Z, which is pivoted at its lower end to the inner side of the vertical plate H.

I am aware that it is not broadly new to si'A the main axle and the adjustable crank-axle for the land-wheel, of a vertically-adjustable slide mounted upon the furrow-wheel end of the main axle and carrying the furrow-wheel spindle, and a single adjusting-lever coperating with said slide and with the crank-axle, to simultaneously raise or lower both the land both to said crank-arm and to the crank-axle' of theland-wheel, whereby both the land and furrow wheels may be simultaneously raised or lowered by operation of said single lever.

3. In a sulky-plow, the combination, with the main axle, of the land-wheel crank-axle mounted upon the forward side of the main axle and extending substantially the full length thereof, a vertical guide-plate rigidly secured to the furrow-wheel end of the main axle, a vertically-adjustable slide mounted on said plate and carrying the furrow-wheel spindle, a sleeve loosely mounted upon the adjacent end of the crank-axle and provided with a projecting arm lconnected by a link with said slide, and a lever secured to or formed integral with said sleeeve and also connected to the crank-axle, whereby said sleeve and the crank-axle may be simultaneously rocked in one direction or the other by operation of said lever, to simultaneously raise or lower the land and furrow wheels.

4. In a sulky-plow, the combination, with the main axle and the adjustable land-wheel crank-axle, of a vertically-adjustable slide mounted upon the furrow-wheel end of the main axle and carrying the furrow-wheel spindle, a lever connected with said slide to raise and lower the same, and a connection between said lever and the crank-axle controlled by a second lever, whereby the landwheel and furrow-wheel may be simultaneously raised or lowered by operating the firstmentioned lever, and whereby the land-wheel maybe raised or lowered independently ofthe furrow-wheel by operating the second lever independently of the iirst-mentioned one.

5. In a sulky-plow, the combination, with the main axle and the adjustable land-wheel crank-axle, of a vertically-adjustable slide mount-ed upon the furrowwheel end of the main axle and carrying the furrow-wheel spindle, a lever connected with said slide to raise and lower the same, a rack rigidly secured to said lever, and a second lever connected with the crank-axle and provided with a latch cooperating with said rack, whereby the land-wheel and furrow-wheel may be simultaneously raised or lowered by operating the rst-mentioned lever, and whereby upon disengaging the latch of the second lever from the rack and swinging the lever forward or backward the land-wheel may be raised or lowered independently of the furrow-wheel- 6.
